Neither is an automatic disqualification (which are listed in the summons you receive), but here in Boston, MA, nursing moms and SAHM's without regular childcare arrangements for non-school age kids usually can delay serving. You have to go at the time you are called appear, but when you explain your situation respectfully and acknowledge that when you are not nursing or your kids are in school/daycare that you will serve w/o question, it's not a problem.
